The atmospheric trace gas, methane (CH4), affects the radiative heat balance of the earth. The sources of atmospheric methane are not well understood. Large air samples (1000-1400 litres) of methane ...

Carbon dioxide (CO2) in the earth's atmosphere is considered a trace gas and also a greenhouse gas. Levels of CO2 in the atmosphere are increasing due to anthropogenic activity. Small dry whole air ...

Nitrous oxide (N2O) is the main naturally occurring regulator of stratospheric ozone and is therefore a major greenhouse gas. An automated flask sampling system is used to collect small atmospheric ...
